Note that I don't think the issue I raised is due to 6e6de3dee51a.
I don't have the machine at hand right now. But, again, I doubt this will
fix it.

There are *more* modules processed after that commit. That's all. So
testing would be appreciated.

Can anyone tell us if

https://lore.kernel.org/linux-pm/20221102195957.82871-1-stuart.w.hayes@gmail.com/ (local)

resolves the module loading delay problem?

This patch unfortunately makes no difference on my test system. In my case,
the kernel has already intel_pstate loaded when udev starts inserting a burst
of acpi_cpufreq modules. It then causes the init function acpi_cpufreq_init()
to immediately return once the check cpufreq_get_current_driver() fails. The
code modified by the patch is not reached at all.
